Description
The present invention relates to a kind of wheat seed cortical cell method for tissue separation, be specially adapted to layering milling system flouring technology.
Current flour milling industry is still being continued to use traditional milling method, and its representational technological process is: dirty wheat storehouse, reciprocating sieve, wheat scourers, stone remover (or wheat washer), refiner, water spray before water, wheat wetting storehouse, the mill, shelling, sizing, clear powder, reduction, screen, brush wheat, packing packing.In short, be that whole wheat rolled brokenly grinding, cut open from the wheat skin again and get endosperm and wear into flour.Because the exocarp of wheat seed contains a large amount of crude fibres, in addition, also adheres to many extraneous dirts.Therefore, adopt this method processing, will inevitably bring following bad consequence:
(1), influences pink colour and quality, essential reinforcement process technology (as strengthening sizing system etc.) in order to prevent the very grave kind shelling of crude fibre and color and luster from going into flour.
(2), in mill processes, remain in the dirt on the wheat seed exocarp, to infect inner powder with mixing mutually inevitably at grind materials.
(3), the mixing wheat bran formed based on wheat seed cortical tissue because exocarp can not divest in advance, its crude fibre composition will diffuse to the inner cortex tissue morely, has reduced their maximum feed effects separately on the contrary.
Since the fifties, because world population increases, lack food nutrition, experts more both domestic and external want to improve flour quality by changing the wheat processing method, also once make a large amount of experiments and imagination, as: United States Patent (USP) (patent No. 2867256).BP (patent No. 1399893) etc., but owing to reason such as the cortex isolation technics is immature, all fail to put into practice.
The present invention adopts following method to finish and grinds the skin function from the feature of wheat seed cortex.
Wheat seed is a complicated body, has been divided at physiology all differentiated multi-level cell tissue in aspects such as nutrition and processing characteristics when ripe.Can give full play to the edible or feed value of contained material composition separately according to level if carry out deep processing, then human nutrition and its feeding be had great importance.The present invention is based on such purpose, traditional handicraft is improved.Its technological process is: dirty wheat storehouse, reciprocating sieve, stone remover, refiner, slubbing wheat tempering, head stone roller, two stone rollers, secondary wheat tempering, shelling, reduction, screen, brush wheat, correspondingly abolish wheat flour purifier and sizing system.
Below technology of the present invention is described.
Cortical tissue's characteristic inspire of wheat seed: one deck internal voids district band is arranged between exocarp and the endocarp.Utilize this internal voids, the wheat of clearing up is added low amounts of water, amount of water is regulated according to wheat breed cortical tissue thickness, generally be controlled at about 0.8%, helical stir through being no more than 30 seconds transports (wheat wetting), only can make the exocarp of wheat seed moistening in running time at this section, promptly reach till the above-mentioned interstice coverage band, enter the wet wheat bark mill of slubbing then rapidly, the decortication amount of slubbing bark mill (by the conversion of wheat nature moisture) is controlled between 1.5～2.5%, this is not comprise part in the ventral groove because the weight that exocarp accounts for whole wheat is about 1.5～2.5%(), promptly on the slubbing bark mill, exocarp is sloughed basically.Head grind wheat bran since before grinding water, its water content is about about 20%, reduce to about 14% through pipeline wind fortune oven dry moisture, the water content that the head of so last collection grinds wheat bran to direct storage without any influence.Wheat water content after head grinds can reach the moisture of former wheat or slightly high by about 0.2%, the road grinds the skin process under so just helping, simultaneously owing in the head stone roller, and the friction between roller and the wheat, impel about 10 ℃ of wheat temperature rises, make the cell tissue of wheat seed loose.Take advantage of this good border, the wheat after the labour contractor grinds is sent into two road bark mills rapidly, no longer needs wheat tempering here.
Grind in the skin process in the dried wheat in two roads,, debranning rate generally is controlled at is no more than 2.5～4% according to the required precision of flour and the skin thickness difference of various wheat breeds.Two roads grind the wheat behind the skin, and its moisture is generally got back to original moisture level.Since the friction between roller and the wheat, about 15 ℃ of the about lift-risings of wheat temperature behind two stone rollers.
Two roads grind and to grind the wheat endocarp that goes in the skin, plant the mixture that the part of skin and megarchidium layer, aleurone is formed, its moisture generally about 14%, to later storage without any influence.Mixture is transported to compass screen surface through wind and sieves.The general plansifter that adopts.Being configured to of compass screen surface: upper strata rough segmentation sieve lattice 40-44W steel wire, can extract 0.3～0.5% wheat crushed rices in mixture.Lower floor's sifting screen lattice 8-10 * * bolting silk, oversize can obtain 2.0～3.0% two stone roller wheat brans, and screenings can obtain 0.7～1.0% the concentrated powder in dimension one ore deposit.All kinds of wheat skins by how many classification of coarse-fibred content have improved separately to ox, sheep or livestock and poultry feed nutritive values such as pig, chicken, for rationally utilizing wheat resource and developing the vegetable protein source and opened up new way.
All adopt machinery and the better sand roller bark mill (claiming rice mill again) of processing performance in head stone roller, two stone roller operations, the embryo that grinds the back wheat still all keeps, and increases broken rate and is no more than 0.5%.
Two wheats after grinding water and short just can go into to grind through secondary again.This tempering time can shorten greatly than the tempering time of common process, this is sloughed because grind the exocarp with anti-water permeation performance and the inner cortex of back wheat, Ci Shi wheat is held the latent heat about 40 ℃ in addition, quicken moisture to the wheat internal penetration, so, secondary water and is stored in the wheat wetting storehouse and only need 2-4 hour, can reach endosperm water balance, softness, easily wear into powder, simultaneously, the shortening of tempering time has also reduced wheat vegetative chance in the wheat wetting storehouse, has improved the clean clean degree of flour.
The invention has the advantages that:
(1), simplified clean-up process, method of the present invention, in scale removal process, only need remove the ionized impurity that the external world is sneaked into, so can save on stream to remove wheat scourers or the wheat washer that wheat adheres to dirt, just can thoroughly get rid of the difficult problem of dying embers and sewage disposal, improve the environmental sanitation in production place.
(2), efficient ultrashort mill diagram powder process, to grind wheat strength control flour accuracy, can obtain high rate, the refining coarse grain of high-quality or particulate flour, and can save equipment such as sizing system and wheat flour purifier.
(3), significantly shorten tempering time, and alleviate contamination by micro in the flour.
(4), rationally utilize wheat resource, make product diversification and improve various product and the nutritive value that tackles product, increase society, economic benefit.
